• Just assume that 60 is x% of 80. We have, now, to find the value of x.

We have x% of 80  =  60

=> (x/100) of 80   =   60  ............ ANSWER

........ x

=> -------- of  80  =  60

..... 100

........ 80 * x

=> ------------  = 60

.....  100

=>  80 x  =   60 * 100

............. 60 * 100  ........ 600

=>  x  = ------------  =   -------------  =  75

.................. 80 ..............  8
